NON-REFILLABL E BOTTLE.

SPECIFICATION forming part of Letters Patent N0."769,230, dated September 6, 1904. Application filed November 1'7, 1903. Serial No. I8L4'79. (No model.)

To all whom it may concern:

Be it known thatI, WILLIAM'H. PEARSON, a citizen of the United States, residing in Passaic, in the county of Passaic and State of New Jersey, have invented certain new and useful Improvements in Non-Refillable Bottles; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference beinghad to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

This invention relates to non-refillable bottles; and it has for its object to provide a bottle with an antirefilling means so constructed as to involve comparatively few parts and conventional so far as the shape of the bottle itself is concerned; Furthermore, an antirefilling means constructed substantially as I construct it will be found to prevent the refilling of the bottle not only when the same is standing in any position where its mouth is above the horizontal, but to also prevent refilling where it is standing with its mouth below the horizontal, as where it has been previously exhausted of air. Referring to the accompanying drawings Figure 1 is a vertical sectional view of the mouth portion of a bottle provided with my improved antirefilling means, the bottle being shown as standing vertically. Fig.2 is a view-similar to Fig.1, except that the bottle is standing with its mouth below the horizontal; and Fig. 3 is a vertical sectional view of the mouth portion of a bottle provided with a modified form of my antirefilling means.

In the neck a of the bottle is arranged a dome-shaped part 6, having a threaded connection with a tubular part 0. These parts together form a valve-chamber having communication with the interior of the body of the bottle through the lower end of the tubular part 0 and communication toward the discharge in the neck through apertures d, formed in the sides of the dome shaped part b. The chamber referred to is held in the neck of the bottle either by a ring of cement, rubber, or

' bottle.

other suitable material a. The lower end of tubular part c is slightly contracted and forms a seat f for a conical valve 9, provided with guides it for insuring its always properly seating. The upper end of the tubular part 0 forms a seato' for a balloon-shaped hollow valve.

1', which is only open at the bottom, as at 70. This valve has play in the chamber comprising partsb and 0, between the top of the part a and the valve-seat 2'. Its lower end when it and valve 9 areproperly seating approximately contacts with valve 9. Openings 0? are arranged somewhat nearer valve-seat 6 than the top of part 6, but yet slightly above the line of greatest width of valve ,7' when the latter is seating.

Arranged as above described tubular part 0 projects into the space of the body of the bottle, and so forms an obstacle to the bottles being completely drained. In order to avoid this, the chamber comprising parts I) and 0 may be relatively. elevated in the neck, thus bringing the lower end of part 0 substantially flush with the lower end of the neck, and at 6 a filling of cement may be interposed between the neck and part 0, while at m a ring, preferably of rubber, is crowded into corresponding grooves n 0 and part 6. (See Fig. 8.) If it is attempted to refill the bottle in any position where its neck-opening is above the horizontal, the refilling will be prevented, because gravity cooperating with the influx of liquid will throw the valves against their seats, and so close the openings through which the liquid must pass in order to enter the If it is attempted to fill the bottle with the neck-opening below the horizontal, in which case the bottle must be first exhausted of air, valve fbeing a light body will be floatedby the inflowing liquid, retarded, as it must be, by the valve and carried rela tively upwardly, coacting with the "influx of liquid to press valve 9 against its seat and seating itself. Although the valve j will tend to rise upon an influx of water when the bottle is in the position last described, when the liquid is being poured from the bottle it tends to recede and allow valve 9 to open, this because of the opening 74 in said valve 9, which permits the valve 7' to be filled by some of the outgoing liquid, and thus fall into the top of the dome b. If it were not for this opening 71:, the valve 7' would be buoyed up by such of the liquid as would lodge in the top of the dome b and act to clog the outflow if not to actually press valve 9 against its seat. Of course after the bottle has been left for any appreciable length of time thereafter in its upright position the liquid in valve 7' will drain out therefrom through opening 7:.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent. is

1. The combination, with a bottle, of a valve-chamber arranged in the neck thereof and having an opening toward the body of the bottle and another opening toward the discharge of the neck, a gravity-actuated valve arranged to seat in the opening in said chamber entering into the body of the bottle, and a float-valve arranged to seat in said chamber relatively above the seat of said first-named. valve and below said other opening and en gageable with said first-named valve to force the same against its seat, substantially as described.

2. The combination, with a bottle, of valve-chamber arranged in the neck thereof and having an opening toward the body of the bottle and another opening toward the discharge of the neck, a gravity-actuated valve arranged to seat in the opening in said chamber entering into the body of the bottle, and a float-valve movable in said chamber to a position substantially intermediate of said other opening and of said first-named valve and engageable with the latter to force the same against its seat, substantially as described.

3. The combination, with a bottle, of a valve-chamber arranged in the neck thereof and having an opening toward the body of the bottle and another opening toward the discharge of the neck, a gravity-actuated valve arranged to seat in the opening of said chamber entering into the body of the bottle, and a float-valve consisting of a hollow body having a single opening in the part thereof adiacent said first-named valve and movable into contact with said first-named valve to a position between the latter and the opening toward the discharge of the neck, substantially as described.

In testimony that I claim the foregoing l have hereunto set my hand this lath day of November, 1903.

WILLIAM ll PEARSON.
